4To all whom it may concern.'

Be it known that I, HENRY Rossem. Wenn, Jr., a citizen of the United States, and a resident of East Orange, Essex county, New Jersey, have invented a new and useful Improvement in S ringless Ratchet-Wrenches, of which the fo lowing is a full, clear, and exact description.

My invention relatesto improvements in ratchet wrenches, and the object of my invention is to produce a strong, simple,1easi1y operated wrench which has a removable jaw with ratchet teeth thereon, and an oscillating handle connecting with the wrench head and provided with a tooth to engage the ratchet teeth of the jaw so thatby oscillatinor the handle and turning the wrench, it wilI operate like an4 ordinary ratchet wrench. My invention is also intended to produce a s lit head with a central opening to contain t e rotatable jaw, and adapted 1to1 provide for theeasy removal of the jaw so that a jaw with a desired opening therein or with a die thread therein, can be applied'to the wrench head or removed readil when desired. My invention is especialiy intended to afford a simple strong connection between the wrench head and handle.

Reference is to be had to the accompanying drawings forming a part of this speciiication inrwhich -similar reference characters indicate corresponding parts in all the views. l y

Figure 1 is a broken side elevation partly in section of the wrench embodying my in vention, the wrench being shown open.

Fig. 2 is a side elevation of a modiied form of the wrench.

Fig. 3 is a cross section on the line 3--3 of ig. 4 is a detail of the removable jaw common to the tye of wrench shown in both Figs. 1 and 2, an

Fig. 5 is a cross section on the line 5--5 Of Fig. 2.

The wrench has a cylindrical jaw with a nut opening 11 therein and with raised ratchet teeth 12 around ltscircumferencc. Obviously the opening 11 can be," made of any suitable size or shape, and the jaw can represent a thread cutting die if desired without affecting the invention.

The jaw is carried bg' a split head comprising the members 1 and 14 `which are hinged together, on one side as shown at 15,

and which have a central openin to receive the jaw.y The meeting ends o the head lmembers 13 and 14 can be secured in anyY convenient wa and I have shown.the meniber 14 provi ed with a projecting lip t closing into a corresponding recess 17 of the opposite member.

'The head members 18 and 14: have an in` ternal channel 18 in which the ratchet teeth` laforesaid opening, and to facilitate this ope eration and to form a simple and convenient connection between the head and the handle, a pin 22 is used which extends through the head member 13 and through the end portion 20 of the handle. The head or end ortion 20 of the handle has at its inner cc ge and at one side, a rigid tooth 23 which is adapted to engage the ratchet teeth 12 of the jaw 10, and the handle member 2.1 is referably, though not necessarily, prc vic ed with a Wrench slot 21 at one end.

It will be noticed that this form of wrench has no spring, and it operates substantially like an ordinary ratchet wrench. The han* dle when oscillated in one direction will cause the tooth 23 to engage one of the teeth 12, and when .the handle is turned in the right direction the jaw 10 will turn with it, and the handle can then be turned back toget a new hold. When the wrench is to be used for turning the jaw in the opposite direction it is simply turned over.

Iir Figs. 2, 3 and 5 I have shown a slight modification' of the wrench in which the wrench is provided with head members 25 and 26 having a central opening for the jaw 10, these being hinged together and secured by a pin 27, and at the' opposite ends the members 25 and- 26 connect with the handle 21 by a pin which also serves the purpose of uniting the members. At this point the members are split to receive the iiat end of the handle 21, and the member 25 is re'- cessed als shown at 28 to receive the tongue 29 onf the opposite member 26, while a pin 30 passes through the tongue and groove parts 28 and 29, the pin having preferably a thumb nut 29* connecting with it. The con* nection between the handle and jaw is thev same in the modified construction as in theconstruction shown in Fig. 1. In either case it will be seen thatl have produced a very simple strong springle's's wrench'which it is hardly possible to4 get out of order, which can be readily operated, and in which the jaw can be easily inserted or removed.

Attention is called to the fact that in the construction shown in Fig. 2 the wrench head can be swung open by moving the pin 27 so as to' permit the removal of the jaw 10,'

and the handle can be readily removed by removing the pin 30.

1. A springless ratchet wrench compris- .ing a split head having a central opening,

an internal channel, and an opening through the head Wall from the back of the channel, a .cylindrical jaw having raised exterlor ratchet teeth running in the aforesaid channel, a 4handle extending into theaforesaid opening having a` single rigid tobth at its inner end and near one side `to engage the teeth of the jaw, and a pivot pinvservin to unite the head members to the handle-an as a pivot for Vthe handle.

2. A springless ratchet Wrench `comprisl members and provided at .one side of its pivot; with a single rigid tooth engaging the ratchet teeth of the jaw.
